Summary
Feline osteoarthritis (OA) was diagnosed radiographically in 22% of cats studied. Clinical signs were often absent, indicating potential underdiagnosis of this common condition in older cats.
Area of Science:
- Veterinary Medicine
- Comparative Pathology
- Feline Health
Background:
- Osteoarthritis (OA) is a common degenerative joint disease.
- Feline OA is increasingly recognized but often underdiagnosed.
- Understanding prevalence and clinical signs is crucial for feline welfare.
Purpose of the Study:
- To determine the prevalence of radiographic feline osteoarthritis (OA).
- To investigate the correlation between radiographic and clinical signs of OA in cats.
- To identify potential causes and contributing factors for feline OA.
Main Methods:
- Retrospective analysis of radiographs from 491 cats over one year of age.
- Classification of cats based on radiographic evidence of OA.
- Comparison of age and gender between OA-affected cats and controls using chi-squared tests.
Main Results:
- Radiographic OA was present in 22% (63/292) of cats with diagnostic radiographs.
- Only 33% of cats with radiographic OA showed clinical signs.
- Older cats were significantly more likely to have radiographic OA (P<0.001).
Conclusions:
- Feline osteoarthritis is prevalent, with 22% of the study population showing radiographic evidence.
- A significant disconnect exists between radiographic findings and clinical signs of OA in cats.
- Idiopathic (primary) OA appears to be a common form in the feline population.
